[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS At present, in either a method of placing a golf ball on a tee by hand or a method of automatically teeing up a ball, the place where the tee exists, that is, the hitting place is one as shown in FIG. It is only a clause. Therefore, the stance to be taken for the tee-up ball is substantially limited to one, and it is difficult to practice the stance as the player gets used to the practice. However, it is extremely important to take a stance on the ball, and if there are multiple places to be teeed up, and if the places are changed successively, you will have to retake your stance each time, so it is very practice Density can be increased.

Therefore, in the present invention, a plurality of tee-up locations are provided. An example is shown in FIG. FIG. 2 shows an example in which nine tee-up locations are set. As shown, in the x direction, x ₁ , x ₂ , x ₃ , y
If the positions of the tee-up locations are indicated as y ₁ , y ₂ , and y _{3 in the} directions, the golf player will be given (x ₁ y ₁ ) and (x ₁ y ₂ ) in the vertical direction (y direction). , (X
₁ y ₃ ) is the first column, (x ₂ y ₁ ), (x ₂ y ₂ ), (x
₂ y ₃ ) is the next column, (x ₃ y ₁ ), (x ₃ y ₂ ),
(X ₃ y ₃ ) is further arranged in the next column in a total of three columns. Similarly, three rows are arranged in a direction (x direction) parallel to the golfer. In FIG.
Although the tee is shown at all points for simplicity, in reality, any one of them is selected in a certain order or randomly, and the ball is teeed at the selected place. After hitting the ball, the ball is teeed up at the next arbitrary place, and this is repeated.

Referring to FIG. 3, three locations in the y-direction (vertical to the golfer), ie, (x ₁ y ₁ ), (x ₁ y ₂ ),
The practice when teeing up at (x ₁ y ₃ ) will be described. When first being teed up on the location of 1 fastest previous (x ₁ y _1), the golfer will take a stance in nearby places F _1. When this ball is finished,
Next, the next ball is teeed up at the location (x ₁ y ₂ ). Then, the golfer the ball will take a stance at a location near the F ₂ of its forward from the stance position of the F ₁ for coming to a position moves away from the golfer. When this hitting also ends, the ball is teeed up at the next (x ₁ y ₃ ) location. Then, like a ball and said before is the golfer because of the position distant from the golfer will take a stance near F ₃ forward. In this way, the position of the ball is changed one after another,
The golfer will take the stance that he thinks is best for that, but it will not always be as expected,
You will have to take a stance thinking each time, and practice will be done enough.

As clearly shown in FIG. 3, in the golf practice apparatus 100 of the present invention, a hitting area 101 and a scaffolding area 102 are provided.
As mentioned above, there are multiple tee-up locations. Further, it is preferable to provide a swing area 103 in front of the tee-up area in the hit area. This is for giving an opportunity for a swing after the ball is hit, and a swing may be added during the sequence to extend a tee-up interval. 1
A lawn may be planted in any of locations 01, 102 and 103. Also, in the practice range, it may be difficult to select an appropriate hitting direction depending on the scaffold area 102. In that case, it is preferable to install the turntable 113 below the scaffold area. Make sure the turntable can be locked in place. This allows the golfer to select an appropriate hitting direction within the field of view of the practice range.

FIG. 3 illustrates the golfer's practice in one row in the vertical direction (y direction). For example, in the x direction parallel to the golfer, (x ₁ y ₁ ), (x ₂ y ₁ ),
It is possible to practice while moving laterally as (x ₃ y ₁ ), and the golfer is directed obliquely forward, that is, (x ₁ y ₁₎
y _1), can be a (x ₂ y _2), simply the vertical direction only if brought into practice so that (x ₃ y _3), rather than practice only in the horizontal direction, practice how to take the vertical and horizontal directions stance . Rather than having a fixed sequence like this, if you program the ball to be teeed up at any randomly selected place, you can practice stance taking with more complex ideas Can be. The program can be selected or set by the golfer as appropriate.

The apparatus for automatically teeing the golf ball may be of any type, but the apparatus disclosed in Japanese Utility Model Laid-Open No. 4-88976 described below is most suitable. . In a conventional general golf practice apparatus, a hole is provided in the floor for a golf ball and a tee to move up and down, which hinders the hitting of the ball, but is disclosed in Japanese Utility Model Laid-Open No. 4-88976. This is preferable because the hole is completely closed. In the golf practice apparatus of the present invention, a golf ball elevating unit with a control device disclosed in Japanese Utility Model Laid-Open No. 4-88976 may be provided at each tee-up location.

The skill of golfers is not limited to men and women, and the gap is large. It is said that good golfers tend to use balls with relatively high hardness, and women and golfers with low skills tend to use balls with relatively low hardness. There is no place in the current driving range where golf balls having different hardnesses can be selected and practiced. Therefore, despite the fact that a golf course in practice uses a ball having a hardness suitable for the golfer, the golf practice range cannot practice according to the skill of the person.

It is said that golf balls have a black printed ball (high hardness), a green printed ball (medium hardness), and a red printed ball (low hardness). In the present invention, a golf practice apparatus selects and supplies a type of ball (color ball) such as a ball (color ball) having a hardness or a color suitable for the golfer from among these balls so that the golfer can practice.

Here, the case of selecting the hardness among the types of balls will be described with reference to FIG. A B ball having high hardness, a G ball in the same hardness, and a small R ball are put in respective hoppers, and a golfer can select a ball by operating selection means such as a push button (not shown in particular) at his / her bat. The type is selected, the selected ball is supplied via the chute 104 onto the tee 25 indicated by the dotted line at the waiting position, and teeed up as indicated by the solid line. The ball can be selected at any time by the ball selecting means.

In the golf practice device of the automatic golf ball tee-up system, not only the one disclosed in Japanese Utility Model Laid-Open No. 4-88976, but also a through hole for a ball to enter and exit is provided on the floor. It remains open. While the through hole is open, an unsavory golfer may throw a golf ball possessed by the player into the through hole and press the ball with shoes. If such an external force is applied to the training device, the device will fail. Preventing this is also one of the preferred embodiments of the present invention.

An example of the configuration will be described with reference to FIG. A groove 110 is formed in the floor, a compression spring 111 is accommodated in the groove, and a ball drop prevention claw 112 is attached to the spring. Then, the claw 112 protrudes toward the through hole 2 by the action of the compression spring 111, and the different kinds of balls 40a
Is prevented from dropping below the floor surface through the through hole 2. Preferably, a plurality of spring-claw mechanisms are provided around the through hole 2.
It seems that providing four of them is less likely to be damaged.

The operation of the ball drop prevention mechanism will be briefly described. Ball hitting cycle (see Fig. 13 to
In FIG. 17), when the elevating unit rises and the outer cylinder 5 comes into contact with the slope 112a of the claw 112, the outer cylinder 5 pushes the claw 112 into the floor against the action of the compression spring 111, and the tee 25 The upper ball 40 is teeed up through the through hole 2 of the floor 1. After the ball is hit, the outer cylinder 5 descends and the claw 11
2, the claw 112 again protrudes from the floor 1 toward the through hole 2 by the action of the compression spring 111, and in order to maintain that state, the different kinds of balls 40a pass through the through hole 2 and are inserted into the apparatus. Can not invade. Therefore,
It is no longer possible for a different type of ball 40a to enter the device unexpectedly or by mischief and cause the device to fail.

Next, a description will be given of an elevating unit suitable for attaching to each through hole of the golf practice apparatus of the present invention. In the golf practice apparatus of the present invention, as shown in FIG. 6, the lifting unit can be attached to the through hole 2 of the floor 1 or the floor 1 so that the golf ball can be automatically or semi-automatically teeed up. The device is attached to the through hole 2 and integrated. It is preferable to lay artificial grass 3 on the floor 1. A stopper 4 is attached to the through hole 2.

As shown in FIG. 6, the golf practice apparatus of the present invention has an outer cylinder 5 open at both ends, a middle cylinder 6 slidably fitted to the outer cylinder 5, and a sliding sleeve on the middle cylinder 6. It is provided with an elevating unit composed of an inner cylinder 7 fitted as possible, and it is preferable that the outer cylinder, the middle cylinder, and the inner cylinder be configured to move up and down in the guide cylinder 8. It is convenient to move up and down in the guide tube 8 such that the flanges 9, 10, and 11 formed in each tube move along the slot 12 formed in the guide tube.

Wires 13 and 14 are connected to respective flanges 9 and 10 of the outer cylinder 5 and the middle cylinder 6, and these wires pass through pulleys 15 and 16 and weights 17 and 18.
, So that an upward force is applied to the outer cylinder 5 and the middle cylinder 6. These outer cylinder, middle cylinder, inner cylinder,
The components such as the guide tube and the weight are preferably made of a rust-resistant material. The lower end of the middle cylinder 6 is open, but the upper end is a closed bottom 19 and a small hole 20 is formed in the center. The lower end of the inner cylinder 7 is also open, but the upper end is a closed bottom 21.

An artificial grass 22 similar to the artificial grass 3 on the floor 1 is preferably planted on the closed bottom 19 of the middle cylinder 6. The artificial turf 22 is frequently hit with a club such as wood or iron and is damaged, so that it is preferable that the artificial turf 22 be replaced. It is preferable that the artificial turf 3, 22 is adhered with an adhesive. It is preferable to use a thermoplastic adhesive as the adhesive so that the adhesive can be adhered and peeled off by heating with a burner or the like. For this purpose, the closed bottom 19 to which the artificial turf is attached is preferably made detachable. FIG. 7 shows an example of the configuration.
In FIG. 7, the closed bottom 19 has a shape like a lid for the middle cylinder 6. For example, it is preferable that the closed bottom 19 can be screwed with a screw 23. A slot 24 may be formed in the upper surface of the closed bottom 19 to facilitate screwing.

A tee 25 is fixed to the closed bottom 21 of the inner cylinder 7, and the tip of the tee is configured to protrude from a small hole 20 formed in the closed bottom 19 of the middle cylinder 6. The tees are also preferably made replaceable because they are frequently hit and damaged by clubs such as wood and irons. An example of a replaceable tee structure is also shown in FIG. In FIG. 7, the closed bottom 21 has a shape like a lid for the inner cylinder 7. For example, the closed bottom 21 may be screwed with a screw 26. A slot 27 may be formed on the upper surface of the closed bottom 21 to facilitate screwing. This closed bottom 19 has a small hole 2
8 is formed, and the tee 25 is fixed to the inner cylinder 6 from the bottom thereof by the support 29. The tee support 29 and the inner cylinder 7 are preferably configured so that the tee 25 can be tightened to the closed bottom 21 of the inner cylinder 7 by screws 30.

The tee 25 is formed as a hollow tube made of a flexible material such as soft rubber. As shown in FIG. 7, the flexible tube 31 is connected to a vacuum device 32 from the bottom of the tee, and It is preferable that the ball can be sucked because the ball does not fall off the tee even during automatic teeing. As a vacuum device, a commercially available vacuum pump, vacuum ejector, or the like is sufficient. Also, the tee support 29 may be a hollow tube to which the tube 31 leading to the vacuum device 32 may be connected.

In the golf practice apparatus of the present invention, FIG.
The lowest position, which is the supply position of the golf ball shown in FIG.
The above-mentioned lifting unit moves up and down between the golf ball hitting positions shown in FIG. It is preferable that the outer cylinder, the middle cylinder, and the inner cylinder are not detached from each other during the elevating operation. As the detachment prevention mechanism, it is most convenient to provide a claw-slot mechanism between adjacent cylinders. FIG. 6 shows an example of the configuration.
In FIG. 6, reference numeral 33 denotes a small screw implanted in the outer cylinder 5, 34 denotes a slot formed in the middle cylinder 6 that limits a range in which the small screw can move, and 35 denotes a slot formed in the middle cylinder 6. Small screw, 36
Is a slot formed in the inner cylinder 7 that limits the range in which the machine screw can move. Also, as other detachment prevention mechanisms,
The flanges of adjacent cylinders may be connected to each other by pins, wires, or the like having a predetermined length.

When the ball reaches the hitting position shown in FIG. 8 from the lowest position shown in FIG. 6, the upper end of the outer cylinder 5 comes into contact with the stopper 4 on the floor 1 and the flange 9 of the outer cylinder 5 comes in contact with the flange 9 of the middle cylinder 6. 1
At the same time as 0 abuts, the closed bottom 19 of the middle cylinder 6 reaches the through hole 2 of the floor 1 and forms the same plane as the upper surface of the floor 1 so that the through hole 2 is completely hidden from the eyes of the golf player. To close. Then, the tee 25 on the inner cylinder 7 projects above the through hole 2 of the floor 1. Therefore, the golf practitioner cannot worry about the hole because there is no visible hole at all, and there is no shock to the hand or damage to the club when hitting the hole, and the golf practitioner can feel safe. You can concentrate on hitting.

As described above, when the elevating unit moves up to the hitting ball position, the components collide with each other. The impact or mechanical noise of these collisions should be small.
For this purpose, it is preferable to provide a shock absorbing device for relieving the impact. FIG. 6 shows an example of the configuration. A coil spring 37 is disposed on the outer cylinder 5 so that the coil spring 37 contacts the bottom of the stopper 4 before the upper end of the outer cylinder 5 contacts the stopper 4. It is preferable to dispose a coil spring 38 between the flange 9 and the flange 9 so that the flanges come into contact gradually.

Loading a golf ball on a tee
As shown in FIG. 6, the small screw 33 of the outer cylinder 5 engages with the upper end of the groove 34 of the middle cylinder 6, and the small screw 35 of the middle cylinder 6 engages with the upper end of the groove 35 of the inner cylinder 7. The operation is performed at the lowest position where the driving means described later in detail lowers the lifting unit against the weights 17 and 18.

At the lowest position shown in FIG. 6, the golf ball 40 may be dropped by hand or a club head from the through hole 2 on the floor surface and placed on the tee 25. However, it is preferred that the golf ball itself be supplied on the tee 25 by an automatic supply device. When the automatic supply of the golf ball 40 is performed, the automatic supply device 39 is preferably installed below the floor 1 as shown by a dotted line in FIG. Many automatic ball feeding devices are currently commercially available, and some have been filed with patent applications. Any of these may be used. To give just one example, those disclosed in JP-A-63-5772 and JP-A-63-222782 can be used.

In order to automatically raise and lower the lifting unit and automatically supply a golf ball, it is necessary to detect at least the supply of the ball at the lowest position and the presence or absence of the ball on the tee when the tee is raised. In any case, it is most preferable to detect the presence or absence of the ball by optical means using a light emitting and receiving element. However, the detection of the presence or absence of the ball is currently performed using various other detection switches. You may do it.

In the present invention, the detection of the supply of the ball at the lowest position shown in FIG. 6 is performed by detecting means attached to the entrance to the guide cylinder 8 of the automatic ball supply device 39.
The detection can be performed at various positions, such as by the detection means attached to the inner wall of the tee 25, by the detection means attached to the inside of the tee 25 and the ceiling. Although the illustration of the detecting means is omitted in the drawings, it is only necessary to detect that the ball has been supplied into the elevating unit at various positions as described above.

The detection of the presence or absence of the ball at the tee-up hitting ball position shown in FIG. 8 is optimally performed by the above-described optical means. A light-emitting and light-receiving element may be installed on the floor to receive the reflected light when the ball is on the tee and not to receive the light when the ball is not on the tee. When the ball is not covered by the ball, the light may not be received. When the ball does not exist on the tee, the ball may be received.

Even when the ball 40 is teeed up at the hitting position shown in FIG. 8, the height varies depending on the club to be used. For example, higher for wood, lower for iron, and so on. Then, in this invention, it is comprised so that the height of the tee at the hitting ball position can be changed. FIG. 9 shows an example of the configuration. A tee height control unit 43 including a light emitting element 41 and a light receiving element 42 is provided on the floor surface, and the light emitting and light receiving elements 41 and 42 are connected to an automatic control device 44. The automatic control device 44 is a device that automatically controls the various operations described above and below, and is optimally constituted by a microcomputer.

FIG. 9 shows the golfer 45 in a state where the height of the tee can be controlled by the head 46 of the club in use. When the head 46 does not enter between the light emitting and receiving elements 41 and 42 as shown by the solid line, light enters from the light emitting element 41 to the light receiving element 42 as shown by the solid line and the height of the tee is controlled by the control device 44 at that time. Takes a hitting position of a preset height or a previously set height, but the light emitting and receiving element 41,
42, the head 46 shields light and does not enter the light receiving element 42 as indicated by the dotted line.
Under the control of 3, the drive means described later raises and lowers the above-mentioned inner cylinder 7, and changes the height of the tee, that is, the hitting ball position. Golfers adjust the tee height to their own club while watching the height of the tee. When the desired tee height is obtained, the club head 46 is moved to the light emitting / receiving element 4.
If you get out between 1, 42, the tee stops at the height of the tee, so you hit the ball there.

In a real golf course, the ground is not flat, but rather inclined in any direction. The hitting ball on such an inclined surface can be embodied in the golf practice apparatus of the present invention. FIG. 10 shows an example of the configuration. As shown in FIG. 10, the one-dot chain line indicates a state of hitting the ball forward and down, and the two-dot chain line indicates a state of hitting the ball forward and up. The structure for inclining the floor 1 in this manner is such that a desired inclined floor surface is realized by providing expansion / contraction means at two front places and two rear places so as to surround the golfer 45 and controlling the height of each of them. You may.

An example of a configuration suitable for inclining the floor will be described. As shown in FIG. 10, a sub housing 47 surrounding the lifting unit is provided under the floor 1 and the sub housing 47 is tied to the tee 2 by a ball bearing 48 installed on the ground.
5 is rotatably supported below the vertical direction. Then, at the two left and right floor points in front of the golfer 45, the expansion / contraction means 49 and 50 are installed between the ground and the floor. That is, the floor 1 is tiltably supported at three points of the ball bearing 48 and the expansion / contraction means 49 and 50. As the expansion / contraction means, any mechanism that can change the height or length, such as an oil cylinder, a motor drive, and a screw post, may be used.

With such a three-point support structure, the floor 1
If only the left and right expansion and contraction means 49 and 50 in front of the golfer are controlled for the tilting, the inclination of the floor surface can be changed three-dimensionally to realize a desired inclination surface similar to a golf course. The manner of the tilt control will be described with reference to FIG. 11, but the description of both the left and right sides will be omitted, and the control of the right expansion / contraction means 50 will be described. In FIG. 11, 51
Is a control means for the right-side expansion / contraction means 50, and 52 is a control means for the left-side expansion / contraction means 49. In each case, the light emitting element 41 and the light receiving element 42 are similar to those described with reference to FIG.
The control operation is the same as that described with reference to FIG. That is, when the golfer 45 puts the club head 46 between the elements 41 and 42, it moves up and down between the upper limit and the lower limit.
When it is pulled out, it stops at that position. Its operation is likewise effected via an automatic controller 44. Left and right telescopic means 49,5
If the left and right control means 51 and 52 are sequentially operated with respect to 0, an arbitrary inclined floor surface is realized.

Next, the drive mechanism of the lifting unit will be described with reference to FIG. In the present invention, the flange 11 of the inner cylinder 7 of the elevating unit is connected to the chain 60, and the chain 60 is wound around the driving pawl 61 and the free pawl 62,
The ratchet 61 is driven under the control of the automatic controller 44 via the clutch 63 and the motor 64. Since it is necessary to precisely control the height of the tee, control the inclination of the floor, and the like, the motor 64 needs to use a precision motor having good responsiveness. It is preferable to provide a brake 65 for improving responsiveness. Instead of a chain, a wire, a thin rod or the like having a small extension may be used. Here, the driving means are weights 17, 18
It is composed of a series of elements such as a chain 60, a clutch 63, a motor 64, and a brake 65, but is not limited to such a configuration. For example, the outer cylinder, the middle cylinder, and the inner cylinder can be moved up and down in sequence. Anything is acceptable. For example, an air cylinder, a hydraulic cylinder, or the like may be used.

FIG. 12 shows the teeed-up ball hitting position. At this time, the contact piece 66 on the chain 60 switch _{S 1, S 2, S 3} , ......, the one switch of switch array 67 having a S _n is turned on (conductive), which corresponds to the tee height shown doing. That is, the switch row 67
Are used to adjust the height of the tee 25, and the switch array 67 is input to the automatic controller 44. As described with reference to FIG. 9, when the club head 46 is inserted into the control means 43, the control device 44 drives the motor 64,
The chain 60 is rotated. At this time, the contact piece 66 reciprocates in the switch array 67 under the control of the control device 44, and raises and lowers the tee 25. For example, the switch S ₁ has a height at which the tee 25 is submerged in the artificial turf 3, and sequentially sets S ₂ , S ₃ ,
..., The height of _Sn and the tee is increased, and S _n is set to the highest height and corresponds to the highest height when teeing at the tee ground.

A contact piece 68 is provided on the chain 60. The rotation of the chain 60 causes the inner cylinder 7 to move as shown in FIG.
When the contact 68 comes to the position where the switch 69 is turned on while being lowered downward as seen in step 2, this signal stops the motor 64 via the control device 44 and stops the lifting unit at the lowest position as shown in FIG. . As described above, the drive device controls the lifting / lowering unit including the outer cylinder 5, the middle cylinder 6, and the inner cylinder 7 to move up and down between the lowest position (FIG. 6) and the hitting position (FIG. 8). In 12), the height of the tee 25 is controlled. The tee height control mechanism at the hitting ball position may be provided separately from the above-described drive mechanism. In this case, under the control of the control device 44, it is necessary to synchronize with the drive mechanism.

Finally, in the golf practice apparatus of the present invention, the ball is supplied at the lowest position in the standby state, automatically tees up to the hitting position, and returns to the original standby state after the hitting. FIG. 17 and FIG.
This will be described with reference to the flowchart of FIG.

FIG. 13 shows that the elevating unit is in a state of waiting for the supply of the ball at the lowest position. That is, the contact piece 68 on the chain 60 of the drive mechanism conducts the switch 69, and stops the elevating unit at this position. Then, the inner cylinder 7 pushes the middle cylinder 6 and the outer cylinder 5 down to the lowest position against the force of the weights 18 and 17 attached to them. Between the upper end of the outer cylinder 5 and the floor 1, an automatic ball supply device 39 for supplying a ball is provided.

In the state shown in FIG. 13, the ball is automatically supplied from the through hole 2 of the floor 1 by hand or the club head.
From 9, the ball 40 is supplied toward the open upper end of the outer cylinder 5. FIG. 13 shows a state where the ball is being supplied from the automatic supply device 39. The supplied ball sits on the tee 25 as shown in FIG. The supply of the ball is detected by the ball sensor 53, and the signal is input to the automatic controller 44. With this signal, the motor 64 drives the chain 60 in a direction to raise the inner cylinder 7.

When the chain 60 is further driven in the direction to raise the inner cylinder 7, the upper end of the outer cylinder 5 comes into contact with the stopper 4 to be in the state shown in FIG. The middle cylinder 6 and the outer cylinder 5 are raised by respective weights 18 and 17.
At this time, if the coil spring 37 is wound around the outer circumference of the outer cylinder 5, the coil spring 37 first contacts the stopper 4, and then the upper end of the outer cylinder 5 smoothly moves against the stopper against the spring force of the spring 37. You can sit down.

When the chain 60 is further driven to raise the inner cylinder 7, the middle cylinder 6 is raised by the action of the weight 18, and the flange 10 of the middle cylinder 6 comes into contact with the flange 9 of the outer cylinder 5. At this time, the upper surface of the closed bottom 21 of the middle cylinder 6 is
And the closed bottom 21 is the floor 1
Is completely closed. The artificial turf 3 on the floor 1 and the artificial turf 22 on the bottom 21 form a continuous lawn, and only the tee 25 protrudes from the lawn. This state is shown in FIG. When the coil spring 38 is wound around the outer periphery of the middle cylinder 6, the contact of the flange 10 of the middle cylinder 6 with the flange 9 of the outer cylinder 5 is buffered by the spring 38, so that the ball 40 falls from the tee 25. No mechanical noise is produced.

At this time, the contact piece 66 on the chain is connected to one of the switches S ₁ , S _{2 ,.}
, The rotation of the chain 60 is stopped once at the position of the switch, and the tee 25 also stops in a state in which the ball can be hit as shown in FIG. This stop position is one of the hitting positions. As shown in FIG. 17, the closed bottom 21 of the inner cylinder 7 changes to the position of the highest hitting position where the closed bottom 21 abuts the closed bottom 19 of the middle cylinder 6. Can be.

As shown in FIGS. 16 and 17, adjustment of the tee height at the hitting ball position is performed as described with reference to FIG.
The golfer 45 sets the club head 46 to the light emitting / receiving element 4
When light is inserted between the first and second switches 42 and 42, the controller 44 drives the chain 60 in accordance with the signal, and the contact piece 66 switches to and contacts one of the switches in the switch array 67, and the height corresponding to the switch is changed. Now move the tee 25 up and down. When the tee reaches a desired height, the tee stops when the head 46 is put out from between the light emitting and receiving elements 41 and 42 at that position. This completes the preparation for hitting the ball.

When the ball 40 placed on the tee 25 having the desired height and ready is hit, the ball 40 on the tee 25 disappears. The ball sensor 54 confirms the presence of the ball when the tee 25 is placed on the ball 40 and rises from the floor surface, and continues to confirm the presence of the ball on the tee while the height of the tee is being adjusted. However, the signal does not cause the controller to initiate any operation while continuing to verify that the ball is present on the tee.

However, when the sensor 54 confirms that the ball on the tee has disappeared by hitting the ball once the ball on the tee has been checked, the controller 44 drives the chain 60 in the downward direction of the inner cylinder 7 according to the signal. start. When the chain 60 continues to lower the inner cylinder 7 and the contact piece 68 on the chain 60 comes into contact with the switch 69, the control device 44 stops driving the motor 64 by the signal and the brake 65 brakes the ratchet wheel 61. Then, the rotation of the chain 60 is smoothly stopped, the lifting unit is stopped at the lowest position shown in FIG. 13, and a standby state in which the next ball is supplied.

When the golfer stops at the hitting position as illustrated in FIG. 16 or FIG. 17 and preparations for hitting the ball are completed, and the golfer desires, the club head 46 emits light and receives light as described with reference to FIG. By appropriately controlling the expansion / contraction means 49 and 50 supporting the floor 1 inserted between the elements 41 and 42, the floor 1 can have a desired inclined surface. By hitting the ball on the inclined surface, the same experience as in an actual golf course can be obtained.
In this case, the ball on the tee may fall from the tee because the tee is also inclined. In preparation for this, it is preferable that the golf ball is sucked from the inside of the tee by the vacuum device 32 on the tee. Even when an inclined surface is not formed, the possibility of the ball falling from the tee is reduced by suctioning with a vacuum device.
